Introduction

HDMI-4K De-embedder is a multifunctional interface, which is capable of audio de-embedding the PCM audio stream. HDMI-4K De-embedder has a built-in EDID Management and Pixel Accurate Reclocking, supporting DVI and HDMI 1.4 signals with or without HDCP encryption.
The output signal is reclocked and stabilized using Lightware Pixel Accurate Reclocking technology to remove jitter caused by long cables or poor quality sources.

Installation

1. Connect the desired source to the HDMI input port.
2. Connect a sink device to the HDMI output port.
3. Optionally connect an audio device (e.g. amplifier) to the Phoenix Audio output port.
4. Optionally connect a headphone to the 3.5 mm Jack Audio output port.
5. Optionally connect a laptop or PC to the USB port and run LDC software.
6. First connect the power cord of the supplied adaptor to the DC input, then to the AC power socket.

EDID Emulation
Selecting an EDID
Turn the EDID address rotary switches to the desired position. Use a flat head screwdriver to change the address. The left switch sets the tens value, the right switch gives the ones value of the EDID.

Avoid the use of keys, coins, knives and other sharp objects.

EDID Learning (OUTPUT LED)
The EDID of the sink connected to HDMI OUT 1 can be stored in the user EDID memory:

1. Turn the EDID rotary switches to the desired position (between #62 – #98).

2. Press the LEARN button and keep it pressed for three seconds.

3. The OUTPUT LED turns dark for a second, then provides feedback:
   • BLINKING (green): EDID learning is successful, the EDID is stored.
   • BLINKING (red): EDID learning is failed.

4. The LED turns dark for a second, then shows the state(s) of the connected sink(s).

Please note that the EDIDs stored in the User EDID memory are deleted when the factory default settings are restored.

Further EDID Options
The following functions are available when connecting to the device by LDC:

• EDID learning or importing an EDID, deleting an EDID (from the user memory).
• Exporting an EDID and saving it as a file.
• Creating a custom EDID by using the EDID Editor or the Easy EDID Creator.

Powering Options

The device can be powered by any of the following ways:

• Using the supplied power adaptor (recommended).
• Connect the device to a proper USB port by the supplied cable.
• Connecting an HDMI source to the HDMI input port.
  Make sure that the port is able to supply 5V 500 mA current.

If the power adaptor is connected, it will supply the device independently from the HDMI/ USB ports. If the adaptor is disconnected from the DC input connector the device tries to
use a different power source (HDMI or USB) if it is enabled and connected. (If the adaptor is unplugged from the AC socket but the DC plug is still connected, the device will be switched off and cannot be changed to another power source. Unplug the DC cable from the device to be powered by USB or HDMI.)
The USB and HDMI powering modes can be enabled/disabled via the LDC software.
If you are not sure that your USB or HDMI port has enough power, disable the powering over USB and HDMI by Lightware Device Controller software. If the supplied power over USB or HDMI is not enough, the device will switch off. In the case of any strange behavior of the device, please disconnect the USB and HDMI cables and connect the 5V DC adaptor.

HDCP Management

The HDCP setting of the HDMI input port can be enabled/disabled on the front panel as follows:

1. Turn the EDID rotary switches to ‘01’ position.
2. Press the LEARN button and keep it pressed for three seconds.
3. The lower three LEDs display if the HDCP state is changed:

• HDCP is enabled: LEDs are dark and light up sequentially.
• HDCP is disabled: LEDs light and get dark sequentially.

Software Control – Using Lightware Device Controller (LDC)

The device can be controlled from a computer using the Lightware Device Controller software. The application is available at www.lightware.com (Support / Downloads section), install it on a Windows PC or a MacOS and connect to the device.

Connecting by the USB Port
Connect the supplied USB cable between the device and the computer and start the LDC.
The device is displayed under the USB devices section; select it then press Connect.

Crosspoint Menu
When LDC connects to the device, the Crosspoint menu is shown by default. The input and output port settings are available separately for the video and audio signals. Besides, the following tools are available:

Frame Detector
The ports can show detailed information about the signal like blanking intervals and active video resolution. This feature is a good troubleshooter if compatibility problems occur during system installation.

Test Pattern Generator

The output ports can send a special image towards the sink devices for testing purposes. The settings of the test pattern are available via LDC:

Mode

• On: the test pattern is always sent to the output port.
• Off: the test pattern generator is off.
• No signal: the test pattern generator is switched on if video signal is not detected.

Clock Source

• 480p / 576p / Original video signal: the clock frequency of the test pattern.

Pattern

• Red / Green / Blue / Black / White / Ramp / Chess / Bar / Cycle. Cycle setting means all the patterns are changed sequentially approx. every 2 seconds.

EDID Management

Advanced EDID Management can be accessed by selecting the EDID menu. The software allows to create, modify, delete, import, or export EDIDs. Please note that the factory presets
cannot be modified.

EDID emulation is available only by the EDID rotary switches on the device.
Backup and restore (Configuration Cloning)
This simple method eliminates the need to repeatedly configure certain devices to have identical (non-factory) settings. If the devices are installed in the same type of system multiple times, then it is enough to set up only one device to fit the user’s needs and then copy those settings to the others, thus saving time and resources. Installing multiple devices with the same customized configuration settings can be done in a few easy steps:

1. Configure one device with all your desired settings with the LDC software.
2. Backup the full configuration file to your computer.
3. If needed, make some modifications to the configuration file using a text editor.
4. Connect to the other device that has to be configured and upload (restore) your configuration file.

Firmware Update – Using Lightware Device Updater (LDU)

Preparation
The following are necessary to perform a firmware update:

• Lightware Device Updater software – available on www.lightware.com,
• Firmware package of the device (LFP file) – please contact support@lightware.com.
• Power adaptor to supply the device.

Performing the Update
The device must be supplied with the power adaptor when the firmware is updated.
Supplying the device over USB or HDMI is not recommended for this process.

1. Connect a PC/laptop to the USB port of the device by the supplied USB cable.
2. Start the LDU software and follow the instructions shown on the screen.

Starting the Device in Bootload Mode
If the usual firmware update cannot be performed for any reason, try the following:

1. Press the LEARN button and keep it pressed.
2. Press and release the hidden button.
3. Release the LEARN button. The device is restarted in bootload mode.

Restoring the Factory Default Settings

The settings and parameters can be set to factory default as follows:

1. Set the rotary switches to ‘00’ position.
2. Press and keep pressing the LEARN button for three seconds. When the lower three
   LEDs blink, release the button. The following settings and parameters are restored:
